Alstroemeria named Stalibron

ABSTRACT

A new variety of Alstroemeria plant particularly characterized by its very large blooms, the outer petals of which are distinguished by a mainly light yellow coloration and having very short streaks of a purplish color at each side of a small notch at the tip of its cuneate petals, the inner petals being of oblong form with aristate tips with numerous deep purplish pencil stripes which spread outwardly from the base of the petals to the petal tips on each side of a longitudinal stripe extending along the centerline of each petal; the upper pair of the inner petals being mainly of a considerably darker coloration than the outer petals and the lower one of the inner petals being substantially the same light yellow color as the outer petals. This plant has substantially the same growth and blooming characteristics as its parent with a profuse and continuous production of flowers from Spring through Fall.

BACKGROUND OF THE NEW PLANT

This Alstroemeria clutivar originated as a sport of the variety `Stalbel` (U.S. plant patent application Ser. No. 872,869 filed June 11, 1986) discovered in 1985 in applicant's greenhouse at Aalsmeer, Holland, and was selected for propagation because of its novel and different coloration and flower form than its parent variety and was reproduced asexually by me and under my direction from its own roots with such satisfactory results that asexual propagation was continued through several successive generations, by division of its rhizomes, which conclusively demonstrated that its novel characteristics would hold true from generation to generation and appeared to be firmly fixed.

DESCRIPTION OF THE DRAWING

My new Alstroemeria cultivar is illustrated by the accompanying photographic drawing which, in full color, shows flowers of a blooming umbel of the plant and demonstrates the unique and distinctive coloration and form of the flowers, the color rendition bearing as nearly true to that specified herein as is possible to obtain by conventional photographic procedures.
